The criminal organisation in western Hungary established a multi-level network of companies that turned out fictitious invoices.

In return for a commission they fabricated false invoices for construction companies, with which their customers could reduce their VAT.

Tax agents impounded more than Ft 4 billion worth of properties, bank accounts, boats, jewels, watches and high-value bicycles.

Of the 19 people questioned as suspects, seven were taken into custody by order of a Tatabánya court.

Proceedings were launched regarding budgetary fraud committed in a criminal organisation.
